Volume of alcohol = 4 mL of alcohol
Volume of water required = 194 mL
<h3>What is a dilution factor?</h3>
A dilution factor is a ratio of the solute to solvent. It is used to express how much of the original stock solution is present in the total solution.
Given the following dilution to make:
obtain 200 ml of an isopropyl solution using the dilution ratio 1 : 20 of alcohol to water.
Total volume = 200 ml
Volume ratio of alcohol to solution will be 1/50 * 200
Volume of alcohol = 4 mL of alcohol
Then volume of water required = 200 m - 4 ml
volume of water required = 194 mL
In conclusion, the dilution is done using the dilution factor.

the answer to your question is false
Answer:
Rate of soil loss that is not higher than the local rate of soil formation
Explanation:
A "sustainable" rate of soil loss means <em>"the rate at which soil is lost from a surface is not higher than the local rate at which soil is formed at an area."</em>
We can determine whether a given farm was practicing a sustainable use of soil or not by merely measuring the amount of topsoil at the given farm.
Answer:
20 trillion
Explanation: I googled it and life is impoartant?
Answer:
I'm not writing your paragraph for you, but I'll give you some help on it.
Explanation:
2 animals that will compete are ants
they are constantly fighting for new territory
What happens, is that when the attackers come, the scouts for the defenders spray something (I forget what) into the air. This alerts the more heavily armed troops nearby. If the defenders win, the attacks are driven back to their colony. If the attackers win, the ants in the defending colony are either overrun and killed, or they run. If the attackers win, they find all the larvae in the nest and either kill them to stop the line together, or in some cases, eat them.
Hope this helps.
